Preparative Liquid Handler LH 2.1

Autosampler and Fraction Collector

KNAUER’s new Liquid Handler LH 2.1 allows for the expansion of purification processes with the ability to combine sample injection and fraction collection in one device. A high capacity of sample and fraction vessels meets a flexible arrangement facilitating reinjection of samples to reach new levels of purification. The handler injects samples with minimal loss regardless of their volume – perfect for working with expensive compounds.


• Combine sample injection and fraction collection
• Inject small and large sample volumes with minimal loss
• Expand your vessel capacities
• Flexible arrangement of samples and fractions
• Reinject collected fractions to reach new levels of purity
